8 Claims. (Cl. 66-191) This invention relates to knitted fabrics, and Fig. 10 is a similar view showing the engagemore particularly to a knitted pile tucked fabric ment of a plain presser with a plain presser cam wherein the yarns constituting the same are so to produce a plain knitted stitch. arranged that the fabric may be readily napped Fig. 11 is a chart showing the relative arrangeto give it a ridged woolly appearance, will be ment of the courses., yarns, wales, presser cams, somewhat run-resisting, and of highly attractive pressers and sinkers. appearance. f Fig. 12 is a sectional view similar to Fig. 3,

One object of this invention is to provide a showing a section of a modified forml of fabric knitted fabric of the above nature having a novel wherein the plurality of rows of pile loops is inl@ arrangement of stitches including pile loops interrupted and a row of plain knitted stitches is terlocked with plain stitches and tucks in every inserted therebetween. other course. Fig. 13 is a chart similar to Fig. 11, showing Another object is to provide a knitted fabric the relative arrangement of the courses,` yarns,

The 55 arrangement of the sinkers is shown in the charts II and I3. Two yarns Il and I5 are fed into the machine at each feed (see Figs. 1l and 13) and are acted upon by the sinkers I2 and I3 in the particular sequence indicated throughout the seven wales (Fig. 11) and eight wales (Fig. 13) of the fabrics shown, and then repeated.

.Two special forms of needle beard pressers I6 and I1 are also provided,-the presser IB being termed high cut and the presser I1 plain. These pressers serve to close the spring-beards II of. the needles III at the desired intervals during the knitting operation under the action of presser cams I8 and I9, respectively. The cam I8 is herein termed a low cut" cam and the cam I9 a plain cam. Both of the cams I8 and I9, during the operation of the machine, act successively upon all of the pressers I6 and I1 to cause them to close the beards II at all knitting points except when the high cut presser I6 is engaged by the low cut presser cam I8, at which times the beards I I of the needles It remain open, and the yarn is not cast oif but stays on the needle Il to be carried along thereby and be cast oi with the next stitch, thereby forming a tuck.

In accordance with the principles of this invention, each long sinker I2 is provided with a pair of spaced notches 20 and 2|, whereby the yarn I4 will seat in the notch 20 in front of the needle 'I0 in position to be engaged by the spring beard II thereof at the downward stroke of the needle and carried through the preceding knitting stitch in the usual manner, as illustrated in Fig. 4. The other yarn I 5 will seat in the notch 2| and will be retained in the fabric in the form of a pile loop 22, as illustrated in Figs. 4 and '1. 'Ihe notch 2| is spaced from the notch 2n an amount suilicient to produce a pile loop 22 of the desired length.

Referring again to the chart shown in Fig. 11, the arrangement of the needle-beard pressers I. and I1, the presser cams I8 and I9, and the sinkers I2 and I3 is such that at the rst wale of the rst and all succeeding odd numbered courses, the yarn Il is plain knitted into the fabric as indicated by the letter S due to the use of the long loop sinker I2, the beard presser I1 and the presser cam I8. Also the yarns I5 will be formed into a pile loops 22 at the first, second, third and fourth wales at all courses due to the action of the rear notches 2| in the long loop sinkers I2 upon said yarns I5.

At the first, second, third and fourth wales of all courses the yarns Il will be plain stitched (S in the chart), and the yarns I5 will be formed into pile loops 22.

At the fifth wale of all even numbered courses, the high cut pressers I6 will be engaged by the plain presser cams I! to close the needle beards II of the needles I0 and the yarns I4 and I5 carried over from the odd numbered courses and those engaged at the even number courses will be cast off and knitted into the fabric.

At the sixth wale of each odd numbered course, both yarns Il and I5 are knitted into the fabric in the usual manner by the needles I0, due to the use of the no-loop sinker I2, and the plain presser I1.

At the seventh wale ofthe first and third courses, the yarns are acted upon in the same manner as they were in the fifth Wale-tucks T being formed at the second and fourth courses.

` At the sixth wale of all courses both the yarns I4 and I5 are knitted into the fabric, due to the use of the no loop sinker I 2, the plain presser I1 and the plain presser cam I9, as indicated by "S" in the chart of Fig. 11.

Referring now to the modified form of fabric illustrated in Figs. l2 'and 13, it will be noted `that it is similar in all respects to the previously described fabric with the exception that plain knitted stitches 22 have been inserted in the fabric after the second wale of each course. The insertion of this row of plain stitches further enhances the appearance of the fabric, by slightly separating the rows of pile loops 22 into two groups of two piles each, and thus produces in the fabric a shadow stripe which extends the entire length of the fabric. Such a shadow stripe is due to partial covering of the knitted stitches at this point by fibres brushed from the adjacent pile loops 22 during the operation of 119411211182 As indicated in the chart of Fig. 13, the pattern of stitches, pile loops and tucks repeats itself every eight wales and every two courses in the modified fabric. In this instance, the pile loops 22 occur in the yarns Il in every first, second. fourth, and fifth wale of each course, and plain knitted stitches occur in the third and seventh wales of each course, and tucks occur with both yarns Il and I5 at the sixth and eighth wales.

As will be evident, in both forms oi.' the invention pile loops 22, wherever they occur, are rmly interlocked and held in place in the fabric between successive plain knitted stitches of the yarn I4, the interlocked piles together with the tucks making the fabric substantially run-resisting.

It will also be understood that the first form of fabric as above described, after napping. will have a wool-like series of wide raised ribs separated by slightly wider depressions. In the modified form, in view of the insertionof a plain knitted stitch to separate the rows of pile loops, the shadow stripe formed therein will be positioned at regularly spaced-apart lines across the width thereof.

While there have been disclosed in this speciilcation two forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosures. but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modiiications'and embodiments coming within the scope of the following claims.

Having thus fully described the invention.

what is claimed as new and for which it is desired to secureLetters Patent, is:
